WEAVING TRAFFIC

CROSS WEAVING MAY OCCUR ON ANY TYPE OF HIGHWAY OR ITS CONNECTIONS AND IS A RESULT OF THE CONVERGENCE AND RELATIVELY NEARBY DIVERGENCE OF TRAFFIC STREAMS. A WEAVING AREA CAN BE CONSTRUCTED FOR BUT A FRACTION OF THE COST OF AN EQUIVALENT GRADE SEPARATED FACILITY. FOR SUCCESSFUL OPERATION OF A WEAVING AREA, THE SPEEDS OF THE SEVERAL TRAFFIC STREAMS MUST BE NEARLY EQUAL. UNIFORMITY OF OPERATING SPEEDS CAN BE ACHIEVED ONLY WHEN THE THREE MAIN ELEMENTS OF A WEAVING SECTION ARE PROPERLY PROPORTIONED FOR THE VOLUME OF TRAFFIC TO BE HANDLED. A CHANGE IN ANY ONE OF THESE ELEMENTS WOULD ALTER THE SPEED OF THE TRAFFIC STREAMS, REDUCE THE CAPACITY, AND AFFECT THE OVERALL OPERATION. THE THREE MAIN ELEMENTS OF A WEAVING SECTION ARE:(1) THE ANGLE OF APPROACH, (2)THE WIDTH, AND (3) THE LENGTH. MORE DATA ARE NEEDED BEFORE DETERMINATION CAN BE MADE FOR THE PROPER COMBINATION OF LENGTH, WIDTH, AND ANGLE OF APPROACH FOR VARIOUS VOLUMES AND SPEEDS TO TRAFFIC. THE DATA AVAILABLE SEEM TO INDICATE THAT IF THE MAXIMUM LENGTH IS MORE THAN 900 FT. TRAFFIC STREAMS TEND TO TRAVEL SIDE BY SIDE, RESULTING IN A FORCED WEAVING NEAR THE END OF THE WEAVING SECTION. /AUTHOR/
